AC motor voltage supply is provided by circuit that reduces symmetrical and asymmetrical voltage components |
摘要 |
<p>The DC supply voltage is coupled to a DC voltage intermediate circuit [4] connected to a pulsed inverter circuit [2] using IGBT devices. The output ports [6] connect with a low pass filter circuit [10] that transmit the low frequency PWM components to the AC motor loads [8] and block the higher order harmonics.</p> |
